Randomized trial evaluates GRX-1 expression in nasal polyps and airway epithelial cells, suggesting a regulatory role of ROS.

This research aims to analyze the expression of glutaredoxin-1 (GRX-1) in nasal polyps and regulatory mechanisms in airway epithelial cells.
Analyzed GRX-1 expression in nasal polyps and normal mucosa using reverse-transcription PCR and immunohistochemical staining.
Assessed IL-1 beta-induced ROS formation and GRX-1 expression in airway epithelial cells by flow cytometry and immunoassay.
Evaluated the effects of N-acetyl-cystein and glucocorticoids on GRX-1 expression.
GRX-1 expression in nasal polyps was significantly higher than in normal nasal mucosa (p < 0.05).
IL-1 beta increased GRX-1 expression and ROS formation in airway epithelial cells.
N-acetyl-cystein treatment reduced IL-1 beta-induced GRX-1 expression, while glucocorticoids attenuated ROS formation.
